Painting a wall is a lot life life:

Go up the ladder, paint a part, two steps back down the ladder, get some more paint, back up, paint again, back down for more paint and back up again. Sometimes it's tedious up and down.

Drip a bit. Clean it up before it dries and makes a bad habit. Working hard to make it an even coat. I think I'm done, but some Good Light on myself shows all my imperfections. Fix it. Back up and down the ladder I go, making a mess of myself with paint everywhere.

Maybe it's almost perfect now? I look and realize the wall and I are both mortal; we will not be perfect now, but I'm satisfied with what I've done. 

Things look fresh and new and much better than they did. I and the wall are perfect backdrops for a Beautiful Savior.
